Abstract

The alga Trachydiscus minutus, while being a relatively new subject of laboratory research, is not yet involved ina real biotechnological development. The aim of this study was an elaboration of the intensive growth conditions. A newmedium specifically designed for the cultivation of the alga was composed, and the reasons were discussed. The use ofthe new medium leads to at least 10% higher growth than media previously used. The maximal growth rate of the algaremains the same, but the growth is comparatively higher before achieving plateau-phase, which is due to a bettercomposition. The new medium is significantly cheaper per 1 kg algal biomass. Attention was paid to precise light andtemperature conditions. The separation of Trachydiscus biomass is discussed as an important part of its biotechnology.The biochemical composition of the alga at these conditions is described. The paper is targeted to micro-enterprises inaccordance with their limited resources.
